1.Imported the proxy bundle into apigee portal

2.Generated client_id (consumer key) by adding product and mapping developer.

3.Accessed the sample login page by passing the query param like below. http://velapigee-test.apigee.net/v1/cc/oauth_ac/sampleloginpage?client_id=VQy9zq5k1IfzGwkAlGKkYHPJTE...

4.We are re-directed to “Authorization Form” where we submitted using “submit” button. 5.Once submit, we are redirected to the below url http://velapigee-test.apigee.net/v1/cc/oauth_ac/sampleloginpage?client_id=VQy9zq5k1IfzGwkAlGKkYHPJTE...
